 wherein the fourth shaft is provided with a protrusion protruding toward the second shifting unit, and wherein an end portion of the protrusion comes in contact with the second shifting unit, and 
 wherein a fourth side flat surface is formed on the protrusion provided on the fourth shaft, and the fourth side flat surface of the protrusion supports the second shifting unit by establishing surface contact with the second shifting unit. 
 
     
     
       2. The laundry treating apparatus of  claim 1 , wherein the fourth shaft is formed to be extended from one side of a fourth shaft bracket, the fourth shaft bracket being installed on the door,
 wherein the fourth shaft bracket is formed to envelop at least a portion of the second shifting unit, 
 wherein the cabinet includes a guidance groove configured to accommodate a free end part of the second shifting unit, and 
 wherein, when the door is rotated in the second rotating direction at a predetermined angle, at least a portion of the fourth shaft bracket is inserted in the guidance groove along with the free end part of the second shifting unit. 
 
     
     
       3. The laundry treating apparatus of  claim 1 , wherein the fourth shaft is provided with a first side flat surface formed along a length direction of the fourth shaft and a second side flat surface formed to face into the first side flat surface. 
     
     
       4. The laundry treating apparatus of  claim 3 , wherein the first side flat surface and the second side flat surface are formed to be parallel to one another. 
     
     
       5. The laundry treating apparatus of  claim 3 , wherein the cabinet is provided with a fourth shaft detachable part configured to accommodate the fourth shaft,
 wherein an receiving groove is formed in the fourth shaft detachable part, the receiving groove being configured to accommodate the fourth shaft, and 
 wherein a width of an opening of the receiving groove is larger than a width between the first side flat surface and the second side flat surface. 
 
     
     
       6. The laundry treating apparatus of  claim 5 , wherein a stopper is formed on the fourth shaft detachable part, the stopper being configured to limit a rotating angle of the fourth shaft,
 wherein a third side flat surface corresponding to the first side flat surface of the fourth shaft is formed on the stopper, and 
 wherein the first side flat surface establishes surface contact with the third side flat surface. 
 
     
     
       7. The laundry treating apparatus of  claim 2 , wherein the second shifting unit is provided with a first side surface facing into the fourth shaft and a second side surface facing into the first side surface,
 wherein the fourth shaft bracket is provided with an extended part configured to be extended along the second side surface of the second shifting unit, and 
 wherein, when the door is rotated in the second rotating direction at a predetermined angle, the extended part of the fourth shaft bracket is inserted in the guidance groove along with the free end part of the second shifting unit. 
 
     
     
       8. The laundry treating apparatus of  claim 7 , wherein, when the door is rotated in the second rotating direction at a predetermined angle, the second shifting unit is being supported on an edge of the guidance groove by the extended part of the fourth shaft bracket. 
     
     
       9. The laundry treating apparatus of  claim 2 , wherein the fourth shaft is connected to a hinge arm, the hinge arm being extended from the fourth shaft bracket. 
     
     
       10. The laundry treating apparatus of  claim 9 , wherein the fourth shaft bracket is provided with a bracket body and the hinge arm,
 wherein the hinge arm is formed to be extended with an inclination from the bracket body and toward the fourth shaft detachable part, and 
 wherein the bracket body, the hinge arm, and the fourth shaft are formed as a single body. 
 
     
     
       11. The laundry treating apparatus of  claim 10 , wherein the hinge arm is configured of two arms each being spaced apart from one another at a predetermined distance, and
 wherein the fourth shaft is provided between the two arms. 
 
     
     
       12. The laundry treating apparatus of  claim 1 , further comprising:
 a lock configured to limit movements of the rotating shaft shifting unit. 
 
     
     
       13. The laundry treating apparatus of  claim 12 , wherein the rotating shaft shifting unit is provided with a first shifting unit being extended along a horizontal direction, and a second shifting unit being extended along a vertical direction from one end of the first shifting unit and selectively and rotatably fastening the fourth shaft to the cabinet, and
 wherein the lock is configured to fix a position of at least any one of the first shifting unit and the second shifting unit. 
 
     
     
       14. The laundry treating apparatus of  claim 13 , further comprising:
 a first coupling part and a second coupling part each being provided to be spaced apart from one another at a predetermined distance along a moving direction of the first shifting unit, or each being provided to be spaced apart from one another at a predetermined distance along a moving direction of the second shifting unit, and being detachably coupled to the lock, and
